What is Check Fraud?

If you are the proud owner of your own retail business, you are probably familiar with just how dangerous it can be to accept checks in general. There are a lot of false checks in circulation, as well as fraudulent ones that don’t even have a legitimate account to be linked to. You may not be aware of just how much a security camera will be able to help you in your business and put an end to this type of problem from happening. They will help you to apprehend the suspect and make sure that they are properly punished to the fullest extent of the law. Having a security camera right above your cash register is one of the best ways to prevent this type of behavior from happening in the first place. When your camera is properly placed you are going to make it virtually impossible for someone who is writing a fraudulent check to be able to disguise their true identity. This is one of the best deterrents out there today. Combining the cameras with the footage that you recorded will be one of the most powerful pieces of evidence when you are faced with the thief in court and need solid evidence.

One of the main problems that you are going to face as a retailer when dealing with check fraud is catching the act before it is too late to do anything about it. The last thing you want is to let the criminal skip town and make a clean break before they can be prosecuted. Another complication is making sure that the footage is not recorded over because you don’t have enough free space to be able to hold all of the images on your recording device. When you have an effective DVR you are not going to have to worry about this problem in the future. You will be able to choose the perfect equipment for all of your needs to make sure that the security camera footage is going to stick around for a very long time. This will help you to keep the perfect records of any potential activity that will help you nail the perpetrator of the crime, regardless how long ago it happened.

When you are dealing with this particular type of theft or fraud, security cameras are going to be one of the best components to solving the problem. There are other options that you can look into as well to compliment your security system, but you should always be prepared. You can also look into some of the software on the market that will monitor your account balances and make sure there are no dramatic changes that occur, as well as other deterrents to prevent your business from having to deal with fraud.

What about Credit Card Theft?

The necessary steps that you need to take to eliminate the potential for credit card theft are pretty similar to that of check fraud. One of the first measures that you are going to need to take for defending your business against this threat is having a high definition camera installed by the cash register to make sure that the transactions are monitored at all times. Another important place to install a security camera is on the entryways into your business. Whenever you are dealing with the security in your retail storefront you are going to have one key advantage that the online businesses will not. You will actually have contact with the people who are doing it and be able to see them. Provided you have the proper security cameras in place, you will be able to stop them in their tracks and make sure they are apprehended.

Whenever you are dealing with the security of your retail business you need to make sure that you have more than just a couple cameras in place. You will also need to make sure you have a top of the line DVR and a complete security package. There are numerous resources available for you to learn what you can do to prevent credit card fraud from happening using a lot more than just your simple camera. Even though you may not be able to pinpoint when the crime is going to occur, you will have your eyes on the criminal at all times and make sure that your business is not a repeat target for offenders. Take the time to invest in your business by doing the necessary research to make sure that you are choosing the perfect security system for your business. You don’t want to become the victim because of a simple mistake that can be made by putting all of your faith into one camera. Even though having a security camera in place is an extremely effective deterrent, you need to make sure that your bases are covered in more ways than one.

How Difficult is Sweethearting?

Sweethearting has long been one of the most difficult to catch forms of theft for retail business owners. It is essentially the practice of having the employees and cashiers giving away merchandise to people they know for free. You may also find a lot of discounts appearing or ringing up orders incorrectly on purpose as a way to be able to give something to their friends and family for a far cheaper price than what it should be, if not free. There are numerous ways that this type of transaction can go down and it may be harder than you think to be able to pinpoint it all down to the wire. You may see that items are not scanned at all, or if they are the price is a lot less than what it should be. It may also involve the employees swindling small amounts of money and then proceeding to hide it with various fixes of accounting errors.

The following are a few different ways that you may see employees attempt to steal your money through various forms of sweethearting:

• Failure to scan merchandise in the first place or improperly scanning it.
• Going over your existing prices and giving a large discount on the more expensive items in your establishment.
• Providing refunds for an item that was never returned, as well as giving a refund for an item that is far more substantial than what the cost of the original item purchased was.
• Voiding a transaction without cause, yet the merchandise is still exiting the premises.
• Handling sales invoices improperly or not entering them at all.

All of the aforementioned items are going to be more difficult to catch and sometimes even the highest forms of security software are not going to be able to do the job perfectly all the time.

The only way that you are going to be able to get the evidence that you need to be able to prove that this is happening is through video recorded from your security cameras. Hence, the video camera that is pointing at the cash register will be your main point of focus once again. It is imperative that you do not let this slip through the cracks if you want to make sure that your business is protected. You will be able to have the peace of mind in knowing that every movement that your employees make will be caught on tape and recorded for later viewing. If you do happen to see something suspicious on the recording that concerns you with sweethearting, you will be able to go back through the tapes and review the footage for yourself to see what the evidence has in store for you.

When you are talking about this specific type of security, you are going to want to make sure that you have the best footage out there. This is one of the reasons why an HD camera is going to receive the top recommendations for making sure that your register is protected at all times. You can choose to buy your high definition camera and DVR at the same time to make sure that you receive the best pricing around and that you are not missing out on any vital components of your security system.

In short, there is more than one way for a potential thief to take advantage of your business and it is up to you to protect yourself. If you choose to sit back and do nothing about it, you are going to see your profit margin flying right out the window. This is going to affect how long you are going to be able to stay in business and think about all of the employees that you have who are loyal and reliable. What will happen to them? Security cameras have been proven to be on the most effective tools of the trade for protecting your business for years and they are not going to stop any time soon. You can make sure that you have the right tools and the right equipment to becoming a victim. When you have the proper security system in place you will be able to stop a thief dead in their tracks; however, if they do manage to get away, you will have the proper security footage to catch up with them later on and recover what you lost in the process.

When you take the time to invest in a security camera you are investing in a lot more than just your business, you are also investing in your future and the future of your establishment. Your employees will thank you for making sure that they are protected and don’t have to feel safe in the event of a crisis or potential threat. Check into your new DVR security system today and see how much it can do for your business in no time at all. You will love the freedom that it is going to bring to the table.

Security DVR Viewer Technology Allows People to Streamline Security Video Streaming

Security DVR ViewerA closed-circuit television system is a step in the right direction, but a security DVR viewer device is necessary for anyone who wants to keep a record of suspicious activity. They fit the bill for anyone who wants to gather evidence and display it later. There’s an old phrase in computer science that refers to ‘write once, read never’ technology. This same statement applies for the security industry as well. If one has no way to look at information after it is recorded, it has essentially been sent off to the bit bucket. The bit bucket more or less refers to the waste cans that were used with paper tape based computers. This means that information that has no way of being recovered is completely useless, and we’re still stuck with that limitation in the modern day.

Everyone wants to be able to view his or her security films for obvious reasons. Just as there is more than one way to skin a cat, there is more than one way to record information in a format that is easily recovered. Technically, one could use a regular VCR or even a specialized VCR that can make the most out of a standard VHS tape. However, VHS tapes are prone to failure and take up a lot of space. DVR technology has become more widely accepted in the last few years because it doesn’t have these limitations. However, people should still familiarize themselves with the shortcomings of digital video recorders.

A DVR hard drive is generally not intended for long time storage, which might make DVD or VHS technology slightly more attractive in some situations. There is limited hard drive space, which means that eventually, footage will end up being rewritten. Just like the hard drive in a personal computer, a DVR’s hard drive could eventually crash into the disk platters and end the life of the machine.

Moreover, some people have expressed privacy or security concerns about digital video recorders. This is probably extremely startling to anyone who wants to use a security DVR viewer. Certain DVR models are designed to send back data about television viewer habits, which is where the source of this concern comes from. First of all, a DVR system that isn’t connected to a network cannot do this. This concern also has to do with the sorts of DVR units that are shipped to television customers from cable and satellite providers. It has nothing to do with security DVR viewer machines. No one should have to fear this trusted technology for use with CCTV systems.

On the other hand, there are plenty of advantages to security DVR viewer technology. There isn’t any external media involved with a DVR. Instead, the unit itself contains the hard drive that is recorded on. If people tend to misplace videotapes or DVDs, this could be great news. The machine could record in high definition, and while this usually isn’t a concern when working with security cameras, it might be nice for certain types of installations.

Security DVR viewer machines that are connected to the Internet or a private network should still not prove to be much of a security risk anyways. After all, these are not in any way connected with the type of DVR devices used for recording television programming. The only similarity that they share is from a pure technology standpoint. The implementation of the technology is very different. If one is sure that their digital video recorder is designed for use with CCTV cameras, then that have no reason to be afraid of any strange security leaks. The type of data that offending DVR devices collect wouldn’t have anything to do with security any ways, so those who have repurposed technology in the past probably haven’t even made something that could successfully interface with the data collection servers in question. While it’s good to keep an eye on privacy issues, some of the rumors that are going around in the security equipment supply industry today are slightly overblown. Nevertheless, people should always be vigilant when told that there is some type of weakness inherent in their equipment.

Networking can work in favor of surveillance specialists, however. Once people get over their fear of security on the World Wide Web, they might realize how many uses an IP camera and IP equipped digital video recorder unit has. One could theoretically capture footage from cameras that are located all over the country or even the world. Security companies that are charged with monitoring various clients could use this to ensure that an electronic eye always monitors each individual camera. Some DVR units are designed to work with 4, 8, 16 or even 32 channels. While these are often more expensive than regular units, their price tag is far lower than having to individually purchase DVR machines for each individual camera. Those systems could also be used to monitor multiple cameras at once through a networking system.

Once again, this would be very useful for those sorts of security firms that have to monitor a large number of different cameras. Pretend, for a moment that there were three different factories that had separate CCTV networks, and all three of them were contracted out to a single location. That single location could use a digital video recorder that was outfitted with Internet protocol networking, if each of the cameras at these factories had an IP module. As long as a solid Internet connection was always maintained, there wouldn’t be an interruption of service.

Security Camera SystemsThat being said, the fear of security that most people have is well placed. There are good reasons to care a great deal about plugging all the holes that a system like this has. A security DVR viewer system is generally pretty foolproof, but there are chances that the network might be hacked. It is usually a pretty good idea to have some sort of Firewall installed on the network that interfaces with the rest of the equipment. Regular virus and spyware checks are necessary to ensure that the network is safe enough to continue to stream video to the recording device.

A second concern involved in using an IP equipped security DVR viewer involves the stability of the Internet connection used. Needless to say, no one could use a dialup connection to network their video cameras, but just because a system is based on broadband technology doesn’t make it stable. Continuous outages won’t do anyone any favors. Weather and other concerns can actually influence connectivity. On the other hand, some people might trust the connection that they’ve previously been working with for their business. For those that have a local area network that seems stable, it shouldn’t be too difficult to get a system like this configured. A few basic computer skills can do away with the hard part of surveillance.

Then again, there are plenty of options with DVR software that runs on regular computers. For instance, JPEG surveillance DVR technology can take individual images and load them onto a computer server. These pictures are in a format that can be read by the majority of personal computers that are running industry standard system software. If a website was set up to request appropriate log in credentials, it could be used to display regular security DVR viewer images. JPEG files are often used on the World Wide Web as it is.

There’s another way this can benefit businesses as well. Pretend that a store has just, unfortunately, been stolen from. If a JPEG image of the suspect came out of the video feed, it can be extracted using security DVR viewer software. This image can then be posted on the store’s regular website, or even printed and distributed. This is not to say that criminal activity should be turned into something sensational, or even encouraged. Instead, these images can be used to try and find the perpetrator of a crime.

When people see the image, they might be able to provide some information about the individual’s identity or whereabouts. Numerous crimes have been solved because of anonymous tips or people leaving a bit of information with the authorities. There’s nothing that states that this sort of thing can’t be part of a real grass roots movement to ensure that justice is served. The fact that this sort of system is in place might also make would-be shoplifters think twice about swiping something from a store that has prepared itself to deal with criminals. Shoplifting can quickly add up and become extremely expensive.

Just like digital video recorder systems that can be connected to the Internet, it is easy to accept a video feed from over the Internet and stream it to a personal computer. In fact, this might be even easier. There are a few special devices that are necessary to turn a computer into a DVR machine, but they aren’t anything that is too difficult to work with. If a camera already has a USB interface, it could actually connect directly into a computer. Of course, IP modules that are present on Internet security cameras will interface with computer recording software just as easily.

There’s no reason that a creative set up involving digital video recorders, IP cameras, traditional CCTV technology and computers can’t be set up. Some vendors actually make a type of video interface that can be installed into a computer motherboard to accept RF video input from coaxial cable feeds. These cards plug straight into an expansion slot, and have a female BNC jack that accepts a traditional feed straight out of a regular security camera. This can be used to turn a computer into a combination DVR and security DVR viewer machine. It might save some money, depending on how much would have otherwise been spent on setting up external equipment.

There are numerous uses of this sort of technology outside of the surveillance market. Some people who are adventurous might want to use a security DVR viewer to record some sort of social networking footage and store it before posting it. This might seem silly, but Internet video market is quickly growing. Of course, a clip of video can easily be taken out of a computer interface and posted on a store’s website to work in much the same way that the previous JPEG example did. A bit of video can be very useful when trying to identify a suspect, and might even be handed over to investigators or a news service.

Some people have used surveillance systems to monitor construction projects. This can be used to make sure that no suspicious activity occurs at the construction site, and it also provides interesting footage for those who are having a house built for them. Naturally, security DVR viewer equipment that interfaces with the World Wide Web allows people to watch this sort of thing from anywhere. For that matter, there might be some interesting applications that involve mobile devices.

Smartphone Video SurveillanceSmartphones and tablets are very popular, and many people have them. If a video link is provided via the Internet, even the most basic mobile phone web browser can be turned into a security DVR viewer. Even if a business owner has to travel across the country, they can still investigate suspicious activity and keep an eye on their business. If they have the right type of equipment, they should be able to check things out from anywhere in the world that has a cellular phone network capable of supporting such devices.

Keeping tabs on a business from the palm of one’s hand is pretty impressive, but it doesn’t mean that the innovations have to end there. There are numerous interesting things that can be done when setting up security DVR viewer technology. Some television sets have picture-in-picture, and this opens up an entirely new avenue for those working with traditional setups. One could watch yesterday’s happenings while keeping an eye on the premises. People are really only limited by the creativity of their engineers.



Security System Camera DVR

Monday, May 24th, 2010

A security system camera dvr or digital video recorder is one of the most common security and surveillance packages used by homeowners, police departments, security agencies, governments and many businesses today. Modern technological advances have yielded a variety of interesting and useful features while keeping prices affordable for not only corporate applications, but for residential applications as well.

A typical security system camera dvr includes one to several cameras, a processor, a monitor, and a dvr. There are many features and upgrades that are available for the security system cameras. The following paragraphs cover some of the most popular and useful features.

Cameras can be categorized based on where they will be used. There are basically two types of cameras based on there placement location: Indoor and outdoor.

Security system camera dvr that monitor and record outdoor activity usually utilized outdoor cameras. These cameras are designed for use in outside environments where they are subjected to weather and other environmental elements. Outdoor security system cameras are normally contained within a case that protects the camera from exposure to dust, water, and other objects. These cameras are often rated based on an International Electrical Code standard known as an Ingress Protection or IP rating.

An IP rating stands for Ingress Protection rating. Cameras for a typical outdoor security system camera dvr usually have a rating of IP66 or IP67. IP66 means the camera is protected from dust and powerful water jets. IP67 means the camera is protected from dust and can be immersed in water up to 1 meter in depth.

Indoor cameras for a security system camera dvr to not have the enclosure that offers protection from the elements as this is not necessary.

Both indoor and outdoor cameras for security system camera dvr may be “wired” or “wireless.” Digital security cameras capture the target area image and transfer it into electronic signals that can be sent to a process or where they are used to recreate a video image. “Wired” cameras send this electronic information via a coaxial cable that is run from each camera to the processor. “Wireless” cameras do not require this coaxial cabling. Instead, a wireless security system camera dvr transmits its electronic information via on-board antennae located on the camera. The only wiring required for wireless cameras is a small line needed to supply power to the unit and on some models; this is replaced with rechargeable batteries.

Digital cameras used for a security system camera dvr can produce a video image in high quality color or black and white; most cameras produce a high quality color image of 420 lines of resolution.

Indoor or outdoor cameras, including both wired and wireless models can also be purchased as day/night vision cameras or as infrared (IR) night vision cameras. Day/night vision cameras produce a high quality color video image using available light. IR night vision cameras for a security system camera dvr produce a high quality monochromatic or black and white video image using near infrared spectrum illumination.

Day/night vision cameras have a very sensitive electronic image sensor circuit that can produce video images in extremely low light conditions such as outdoors at night with no moonlight. However, these cameras must have some visible light available to produce the image, even if the available light intensity is very low.

Night vision IR cameras have a special IR sensitive electronic image sensor circuit that can produce normal color video during daylight conditions, but utilize IR radiation to create a high quality monochromatic video. These cameras normally contain IR Light Emitting Diodes or LEDs that emit IR light. IR light is invisible to the human eye, so these cameras can work undetected in total darkness with no available visible light.

Other functions for cameras include pan, tilt, and zoom (PTZ) options that allow the camera to move about and change its target area or field of view as well as utilize telephoto lens technology to enlarge objects. These features can be controlled manually by remote control or automatically by programming which can be used to track objects or individuals. An example of automatic PTZ is tracking the movement of a car through a parking lot or an individual in a specified area.

Security system camera dvr records the video images in the form of a video data file on the dvr for later viewing or archival purposes. Further, the dvrs can be purchased in a variety of storage capacities to fit any application.

A security system camera dvr or digital video recorder is one of the most common security and surveillance packages used by homeowners, police departments, security agencies, governments and many businesses today. Modern technological advances have yielded a variety of interesting and useful features while keeping prices affordable for not only corporate applications, but for residential applications as well.

Home Security Standalone DVR System

Monday, May 24th, 2010

A home security standalone dvr system can provide the security and peace of mind for most residential applications. Huge selections in camera types, video recording technologies and monitoring options have made digital video camera systems the ideal choice for home security and monitoring.

Exactly what is a home security standalone dvr system? A home security standalone dvr system consists of the following components:

• Digital video cameras
• A processor/capture board/and CODEC application
• A digital video recorder or DVR, and;
• A monitor if desired

Digital video cameras for home security standalone dvr systems are manufactured in two basic types, indoor and outdoor. Outdoor cameras are usually “weatherproof” meaning they are able to withstand environmental weather conditions like rain, snow, and heat. Indoor cameras are designed for used in covered environments and do not usually contain the same type of camera enclosure that provides protection from the elements.

Both indoor and outdoor digital video cameras for home security standalone dvr systems can be wired or wireless. A wireless camera does not require an image transmitting cable to be connected from the camera to the processing unit. Instead, these cameras transmit their data via built-in antennae to receiver units that are usually located near the processor, dvr, and monitor. Wireless camera units usually transmit their data on the 2.8 or 5.8 MHz radio band and can provide fairly long line of sight ranges for transmission.

Whether the cameras are indoor/outdoor and wired/wireless they can also be day/night vision or infrared (IR) night vision cameras.

Digital video cameras produce a video image by using one of two different types of electronic sensors, both of which can produce color or black and white video. Charged Coupled Devices or CCDs and Complimentary Metal-Oxide Semiconductors or CMOSs convert captured light into electrical energy that can be used to create high quality video images. CCDs and CMOSs can be very sensitive light and create high quality video in very low light conditions, utilizing as little light that is available on moonlit nights for example. Cameras that use these sensors are usually referred to as day/night vision cameras and although they can operate in very low light condition, some visible light must be available to produce a video image.

There are digital video cameras that can operate in conditions of total darkness. These cameras are normally called night vision cameras and operate by creating video images from infrared or IR light. CCDs have the inherent ability to detect IR radiation light which is invisible to the human eye. A digital video camera for home security standalone dvr system can take advantage of this characteristic by “bathing” the target area with IR light. Since the light is invisible to the human eye, we cannot see or detect the presence of the IR light. IR Light Emitting Diodes or LEDs are used to produce the IR light for this purpose. IR LEDs are placed around the camera lens so they are aimed at the same target area as the camera and illuminate the area to record IR video. IR images are monochromatic or black and white.

The home security standalone dvr system is a security camera system that does not require any additional equipment, such as a personal computer to operate. The cameras transmit their data to a processor or capture device that converts the electronic information sent into a digital video file that can be watched on a monitor and stored on a digital video recorder or dvr. Often a COmpression/DECompression (CODEC) programs or wired circuits are used to reduce the size of the digital file while maintaining high quality video images. This provides for easy storage and portability of the file, allowing large amounts of data to be stored.

The digital video recorder of a home security standalone dvr system is much like the hard drive on a personal computer. It is a magnetic storage disk or plate that stores the video in digital file format for later viewing or archival purposes. Files can even be copied to other mediums and viewed on personal computers or DVD players.

Home security standalone dvr systems can be used to for a variety of applications. They are great for providing perimeter coverage of the residence for security and surveillance purposes. They can also be used inside the home to detect and recorded unwanted intruders. In addition they can be used as bay room monitors, nanny monitors, and pet monitors.


DVR Wireless Security System

Friday, May 14th, 2010

A Digital Video Recorder or DVR Wireless Security System is one of the most popular systems used for security and surveillance applications today. Although there are many variations of a typical DVR Wireless Security System, the general set-up for a security/surveillance application of this type involves the use of wireless Closed Circuit Television or CCTV cameras and a digital hard drive used to record the pictures or video sent to it by the CCTV cameras.

The key components of a DVR Wireless Security System include wireless CCTV cameras with antennas, a high speed digital hard drive, a wireless single or multi receiver, and a digital video recorder. Each of these components serves a specific function to provide a total package DVR wireless security system. Let’s take a closer look at each component.

The wireless camera comes in many varieties. There are dome cameras, box cameras, bullet cameras, PTZ or pan tilt and zoom cameras, and even explosion proof cameras. Wireless security cameras may capture still pictures and/or motion video and may provide the images in black and white or in color. Some cameras also come equipped with a microphone for capturing sound. In addition to these functions, wireless security cameras normally have an on-board transmitter that operates in the 2.4 GHz or 5.8 GHz bands. The broadcast range for these wireless cameras is usually somewhere between 200 and 700 feet depending upon environmental conditions.

The receiver is basically like a radio receiver or in-home wireless telephone receiver base. It receives the wireless signal transmitted from each camera and sends that signal to the DVR. Generally, receivers have more than one “channel”; that is, they can receive signals from more than one camera at a time. A receiver that can handle input from four different security cameras at one time is usually referred to as a four channel receiver.

After the camera’s signal is received, it is normally processed in some way before it reaches the DVR. The processing circuitry is normally found on an electronic “board” that is included with the DVR. This board may have one to several different file compression/decompression or CODECs wired into its circuitry. The purpose of using a CODEC is to minimize the size of the file to be stored on the DVR without sacrificing too much quality.

Digital video is basically nothing more than digital photographs taken at a rapid rate (normally up to 30 frames per second or fps). However, if you consider the digital size of a file for one photograph, you can only imagine the total size for thousands used to create a video. For example, a typical digital photograph may create a file 1.5 megabytes (MB) in size. One hour of video would be 30 photographs per second, times 60 seconds, times 60 minutes or 162,000 MB or 162 Gigabytes (GB) of information! A 250 GB hard drive would be filled in only two hours. However, CODEC boards reduce the file sizes drastically allowing for several hours to days of recording without filling up the hard drive.

Most DVR wireless security systems also include a monitor to view the cameras’ output in real time as well as to view the playback of recorded video. The monitor may be a small wireless unit itself or can be a larger LCD type monitor used with most computer systems.

There are many benefits to using a DVR wireless security system. Technological advances have made the components relatively inexpensive so that these systems can not only be used by businesses but can be used by consumers to provide security surveillance for the home. Wireless systems have the added benefit of placing the cameras in strategic places that are unlikely to be seen by potential criminals and vandals. In addition, DVR wireless security systems do not require signal transmission cables from the camera to the DVR, making installation much simpler and neater as well.
